MIXING-MACHINE.

Specification of Letters Patent.

Application filed May 4, 1911.

Patented Mar. 26,1912.

Serial No. 624,980.

To all whom it may concern:

, Be it known that I, J AMES D. CpoUGH, a citizen of the United States, resident of Lakewood, county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement in Mixing-Machines, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

My invention has reference to a mixing machine, while more particularly to certain specific improvements in connection therewith.

The object is the provision of a more satisfactory machine by reason both of its increased general efliciency and practical fa cility of operation. a

The said invention consists of means which are hereinafter fully described and particularly pointed out in the claims.

The annexed drawings and the following description set forth in detail certain means embodying my invention, the disclosed means, however, constituting but one of various mechanical forms in which the principle of the invention may be applied.

In said annexed drawings :Figure 1 is a vertical section of a mixing machine embodying my invention, a few parts being shown in elevation. Fig. 2 is an end elevation of the same. Fig. 3 is a section on line III-J11 of Fig. 1, looking in the direction of the arrows. Fig. 4 is a section on line IVIV of Fig. 3, looking in the direction indicated by the arrows. Fig. 5 is a perspective view of one operative part. Fig. 6 is a section on line VIVI of Fig. 1. Fig.

7 is a section on line VII-VII of Fig. 6,'

looking in the direct-ion of the arrows. Fig. 8 is a View similar to Fig. 7, with one part thereof slightly moved to one side. Fig. 9 is a top view on line IX-IX of Fig. 7 looking in the direction of the arrows, one part thereof appearing in section. Fig. 10 is an elevation of a specific improvement in connection with the mixing kettle proper.

Referring to the drawings, the machine comprises a bed-frame A having three upwardly extending standards a, a and a Mounted upon suitable bearings in the standards a and a is a driving-shaft a, and in turn mounted upon this shaft are the fast and loose pulleys a and a". The driving-shaft a projects through the bearing in the standard (1 and has fixedly mounted upon the extremity thereof, a driving gear a.

Mounted for tilting movement upon suitable higher bearings formed in the standards a and a and specifically through the further medium of integral gudgeons b, is a saddle B. Supported in any approved manner upon this saddle is the mixing kettle C. This kettle is provided in the usual manner with a steam jacket 0' and a removable cover 0 The saddle B is provided with two depending portions 5 the lowermost extremities of which are of smaller dimensions and indicated clearly in Fig. 1 by the reference letters I). furthermore beveled on one side and at the bottom, as most clearly shown in Figs. 7 and 9, and designated each by the reference letter 5 A manually operable lever b is secured in an upwardly extending boss 6 upon the saddle and a side-projecting boss 0 on the cover, which are alined, as clearly appearing in Fig. 1. By means of this lever, the saddle and hence the kettle may be tilted in the customary manner.

Steam inlet and outlet pipes, designated respectively as b and 5 extend through the gudgeons b, and communicate with the steam jacket. The outlet connects indirectly with the jacket by means of the extension pipes 72 leading from the bottom of the jacket, as shown in Fig. 1. The gudgeon through which the outlet pipe 6 extends is slotted surrounding the point where the extension pipes communicate, this slotted portion being indicated by the reference letter I). This is for the purpose of enabling the kettle to tilt without occasioning an interference between the gudgeon and the connecting pipe, as will. be readily understood.

The gudgeons, in accordance with my invention, are furthermore provided with open air-spaces b surrounding both the steam inlet and the steam outlet pipes,

These extremities are.

whereby an appreciable cooling means is guaranteed. To still further accentuate this feature, however, these air-spaces are provided with a plurality of outlet openings 3), in order that a circulation of air may be established.

Interposed between the inner faces of the saddle and the steam jacket and more specifically between an otherwise direct communication generally established between the steam inlet pipe and the steam jacket, is a distributing member 0 This may be an interposed disk, and in the present instance, for the purpose of illustration, is provided with four diametrically positioned curved nozzle-openings. These openings are so curved and arranged that adjacent openings will distribute the steam issuing therethrough alternately toward and away'from each other, as should be apparent from an inspection of Fig. 10. By this means, it is intended that the steam will be more uniformly and more rapidly distributed throughout the entire area of the jacket, the whirling motion imparted to the ct of steam and the opposition set up between alternately adjacent nozzles, contriving to in sure this more efficient distribution.

Mounted upon that gudgeon b nearest the pulleys a and a, is a loose intermediary gear D, adapted to mesh with the driving gear a and also with a gear 6 which is .positioned upon the extremity of the shaft E, which is mounted upon the saddle intermediately of the kettle-supporting portions proper and the lowermost extremities of the depending members 5 This shaft E is provided immediately opposite the gear 0 with j a driving pinion 6 which is adapted to mesh with a horizontal gear a mounted upon the shaft 0 which extends through the center of the kettle. A pair of rotary paddles c are secured in any satisfactory manner to this shaft interiorly of the kettle, and are properly designed to effect the mixing. A segmental rack 0 is secured to the center of the bottom of the kettle, to surround the gear 0 and depend to within a short distance of the bottom of the frame, as best seen in Fig. 2. It will now be obvious that the rotation on the part of the fast pulley a will be transmitted first to the driving gear a, shown in Fig. 2, then to the inter mediary gear D, and thence to the gear 0 and pinion 6 whereby the gear 0 and hence the shaft 0 are caused to rotate and impart such motion to the mixing paddles c Fixedly mounted upon the longitudinal center of the upper surface of the bed-plate A, are two members F each comprising two oppositely disposed converging ears f, one of which and necessarily the similarly p0- sitioned one in each case, is fashioned with a cut-outportion F, the purpose of which will presently more clearly appear. These ears are moreover so positioned that the lowermost portions 6 of the depending members 5 are normally adapted to rest between them. A rod G is mounted for sliding movement through these members F, and is manually actuated through the medium of the lever g and fixed pivot 9 Fixedly secured to this rod and at a distance apart approximately corresponding to the location of the members F are two wedgemembers each provided with an upwardly extending portion 9*. These members are also provided with two bevel surfaces, namely the side and upper surfaces thereof. The upwardly extending portion 9 is located on that side which is adapted to wedge opposite the cut-out portion f of the member F. The conjunctive relation of these wedge members is such that they are adapted to wedge not only between the sides of the members F, but also underneath the under surfaces of the extremities b of the depending members 6 Furthermore, such wedging action is effective when the upwardly extending portion 9 is precisely opposite the cut-out portion f and hence locks against oscillation, as well as slightly raises the depending portions Z)". The operation of these specific parts will be more readily understood from a close inspection of Figs. 6 to 9 inclusive.

Secured to one side of the bed-plate and in the plane of the segmental rack 0 is a bracket H having one portion h projecting upwardly at approximately a right angle to the arc of the rack. This portion of the bracket is hollow, through the medium of the upwardly disposed rectangular opening 7L and is furthermore provided with a longitudinally extending side opening if, the purpose of which will presently appear. Secured to the rod G and extending in the direction of the bracket is an arm J to which is secured the rod 7", to which in turn is connected a block j extending through the opening 71/ in the bracket. The block 7' is accordingly slidable along with the rod G when the latter is actuated by the lever g, as previously described. This block is provided with an inclined opening j having an upper horizontal portion 7' and this opening intersects the same plane as the side opening in the portion h through which the block 7' is adapted to slide. A toothed member K rests in the upper opening if, and is also provided with an opening in substantially the same plane as and registering with the longitudinally extending side opening k in the bracket. The block and toothed mem ber may therefore be operatively connected through the medium of the pin L extending through the lateral sides of the member K, and having an interiorly disposed roller Z. As should now be apparent, a sliding on the part of the block j through the portion h of the bracket causes the pin L to follow the inclination of the opening 7' and inasmuch as the toothed member is supported upon this pin, it will be raised or lowered in the bracket according to the direction in which the block j is slid. In this manner, it may be caused to engage the segmental rack 0, effect the locking thereof, and hence serve to prevent the further tilting of the mixing kettle C.

Attention is now directed to the fact that two interdependent locking means are provided to preclude the initial tilting of the kettle, and these operate briefly as follows: Assuming the kettle to be in its horizontal position, and the depending members 6 n a substantially vertical position so that their extremities rest between the members F, an outward pull upon the lever 9 will neces sarily have the result of sliding the rod G in the direction of the other end of the frame. A sliding movement on the part of the wedge-members 9 through the members F is necessarily coincident therewith, whereby these may be caused to both look and raise the depending port-ions, as previously described. This raising of the depending portions is exceedingly slight, yet all-sufficient to relieve the journals of the kettle during the mixing operation when the kettle is in 1ts normal working position. The sliding of the rod G in the direction now being considered, will simultaneously cause the block y' to slide in the same direction through the bracket H, and consequently the pin L to slide up in the inclined opening 7', and rest in its horizontal portion 7' With the rising of the pin L, as previously explained, the toothed member K will be raised to engage and fix the segmental rack. A reverse movement on the part of the lever 9 will, of course, serve to draw the wedge-members g and block j in the reverse direction, whereby the toothed member K slips out of engagement with the segmental rack, and at the same time the lowermost extremities b are released and permitted to oscillate over the cut-out portions f when the tilting movement is imparted to the lever 6 This double locking feature is intended not only to effect the more rigid but the more uniform support of the mixing kettle during the mixing operation, and though the support is more rigid, the journals are actually relieved.
